I'm a physics teacher of 30 years. I am teaching Summer School right now and have 3 of my students "cheating" by using your service. I have written hundreds of test questions over my career and have recently realized that your service and others like you have taken my intellectual property (test questions) and posted it with answers on your site without my consent nor with any form of compensation.
I will be checking with an attorney to determine my next move.
How can this be legal?
